Sound waves are caught by the outer ear and directed inward.
they vibrate the ear drum, which vibrates the 3 bones in the ear.
This causes a special area in the cochlea to vibrate, depending on the pitch.
This information is sent to the brain by the auditory nerve where it is interpreted.

The anatomy of hearing is the anatomy of your ears. It consists of the outer ear, the middle ear and the inner ear.
The outer part is mainly your lobed ear which by its anatomy- grooves and oval indented shape, collect and concentrate incoming sound waves directing them into the middle ear. The middle ear composed mainly of your ear canal, lined with sensitive hairs, further concentrates the sound waves into the inner ear where it interacts with the drum and tympanic membrane converting the sound into electric impulses travelling down your auditory nerves.
Your hearing is an important sense that helps you discriminate sounds from loud to soft to even explosive. More than that it is a defense mechanism,helping you survive in dangerous sound levels and trigges your "flee" mode.
If you will notice most audio equipment have near parabolic shapes like your ear.
